Camila Giorgi is through to the second quarter-final of the season in Bronx following a hard-fought 3-6, 7-5, 7-6 triumph over Andrea Petkovic in two hours and 40 minutes. Facing each other for the first time since Dubai 2016, Camila and Andrea pushed each other to the limits until the very last point, with the German taking a couple of points more overall but not those that mattered the most, staying in contention after fending off ten out of 17 break chances.

Delivering similar numbers behind the initial shot, Giorgi suffered eight breaks from 14 opportunities offered to the German, overcoming a slow start to get back into contention and emerge at the top. Andrea made the best possible start, dropping three points on serve in the opening set and forging a 6-3 advantage with a double break, hoping for more of the same in set number two as well.

There, Camila erased an early deficit and stayed in touch with the opponent, taking 12 of the last 16 points from 5-4 down to steal the set and send the action into a decider where they traded six breaks in the first seven games to stay neck and neck.

Giorgi broke in the 11th game to serve for the win, only to lose serve in the next game to deliver a tie break that she claimed 7-3 for the place in the quarter-final. Lin Zhu was forced to retire against Alize Cornet while trailing 7-6, 4-0, overcoming a 5-2 deficit (the encounter kicked off with four straight breaks) and a set point at 4-5 in the opener before Cornet finally clinched it in the tie break.

The Chinese lost the first four games in the second set and decided to retire at 0-40 in the fifth, propelling Cornet into the fourth quarter-final of the season. A qualifier Anastasia Potapova managed to spend only 48 minutes on the court against the 5th seed Katerina Siniakova who led 6-0, 3-0 before the young Russian had to retire.

In those opening nine games, Siniakova fended off both break points she faced and mounted the pressure on the rival who suffered five straight breaks of serve before decided to quit. Bernarda Pera is using her wild card with both hands at the moment, ousting the 3rd seed Barbora Strycova 3-6, 6-2, 6-1 in just under two hours for the place in the fourth WTA quarter-final in 2019.

Strycova lost only four games against Pera in Melbourne last year but the American has improved her game a lot since then, fending off nine out of 12 break chances today and securing six breaks from seven opportunities to rule in the pivotal moments and advance into the next round.

Barbora controlled the pace in the first set, serving well and stealing the rival's serve twice in games seven and nine for a 6-3. Pera responded with an even stronger rhythm in set number two, keeping her serve intact and earning two breaks for a 6-2, boosting confidence and storming over the decider with four successful return games to march into the last eight.
